Margo can purchase tile at a store for $0.99 per tile and rent a tile saw for $18. At another store she can borrow the tile saw for free if she buys tiles there for $1.19 per tile. How many tiles must she buy for the cost to be the same at both stores?

(0.99x) + 18 = 1.19x

18 = 1.19x
      - 0.99x

18 = 0.2x

18/0.2 = x

90 = x
(She must by 90 tiles for the cost at both stores to be the same, Cheers!)
